If the battery of the Hombli Smarter smoke alarm runs out and you are on holiday, there are several measures that are used for protection and notification:

- Notification via Wi-Fi: The Hombli Smarter Smoke Detector is connected to Wi-Fi and can send notifications to your smartphone or other devices when the battery is low or other critical conditions are present.
- Audible warning: Although the detector will give an audible warning when the battery is low, it will not beep continuously. The audible warning is usually limited to a certain duration to avoid constant interference.
- No need for neighbours: Thanks to the Wi-Fi notification, it is unlikely that neighbours will have to break into the home as you will be informed via your smartphone and can take appropriate action.

This ensures that you are notified even when you are on holiday, without causing any undue disruption.
